Multimodal Systems Design with Network Interactions

人们对支持城市交通的多式联运越来越感兴趣。自2000-2001年以来，加拿大政府在联邦公共交通相关基础设施方面投资了50多亿美元，并将公共交通确定为建设加拿大基金下的五个国家优先事项之一。然而，尽管移动技术和其他多式联运商业模式（如Zipcar、SF Park等初创公司）不断发展，许多公共交通机构仍在使用最传统的系统和替代方案进行规划和运营。这是因为计算机模型无法回答，例如，“如果市中心的停车设施费或Zipcar费率得到10%的补贴，汽车、公共交通和自行车的流量将如何变化？”

There is an increasing interest in multimodal transportation to support urban mobility. The Government of Canada invested over $5 billion in federal public transit-related infrastructure since 2000-2001, and has identified public transit as one of five national priorities under the Building Canada Fund. Yet, many public transport agencies continue to plan and operate using the most conventional systems and alternatives, despite the growth in mobile technologies and alternative multimodal transport business models (e.g. startups like Zipcar, SF Park). This is because computer models cannot answer, for example, "How would the flow of cars, transit, and bikes shift if parking facility fees or Zipcar rates in downtown were subsidized by 10%?"
